Baryogenesis via the CKM Matrix with Minimal Flavor Violation
Innes Bigaran, Gordan Krnjaic, Kevin Langhoff +1
It is often claimed Standard Model CP violation is insufficient for baryogenesis. We present a counterexample using minimal flavor violation (MFV) in which all CP-violating effects…
Probing the Cosmic Axion Background via Axion-Photon Conversion in Filaments
Duncan Rocha, Gordan Krnjaic, Matthew J. Baldwin
The cosmic axion background (CaB) is a hypothetical population of relativistic axions produced in the early universe. If the CaB is produced from dark matter decays, the axions in…
New Thermal-Relic Targets for sub-GeV Dark Matter Direct Detection
Xu Han, Gordan Krnjaic
The paper identifies predictive thermal‑relic targets for sub‑GeV dark‑matter particles that interact via light vector mediators, outlining how upcoming electron‑recoil direct‑dete…
Direct Detection of Ultralight Dark Matter via Charged Lepton Flavor Violation
Innes Bigaran, Patrick J. Fox, Yann Gouttenoire +4
We propose a dark matter direct-detection strategy using charged particle decays at accelerator-based experiments. If ultralight dark matter has a misalignmen…
Gamma-Rays and Gravitational Waves from Inelastic Higgs Portal Dark Matter
Dan Hooper, Gordan Krnjaic, Duncan Rocha +1
We explore a simple and predictive dark matter scenario involving a complex scalar field, , coupled to the Higgs portal with no additional field content. In the UV, the field p…
Expected Sensitivity of the Light Dark Matter eXperiment to Long-Lived Dark Photons and Axion-Like Particles
Torsten Akesson, Clay Barton, Charles Bell +53
The Light Dark Matter eXperiment (LDMX) is an electron-beam fixed-target experiment primarily designed to achieve world-leading, model-independent sensitivity to sub-GeV dark matte…
